You have to wonder if the model is going to end up recreating Verlet integration in there somewhere, or if it's generating a pile of those optical acceleration cancelation type heuristics in neural net form.

It's one of those ideas I've had around for a while that if you fused decent object tracking with an understanding of Verlet integration you should, in principle, start being able to measure all sorts of physical quantities quite easily.
